STORAGE-BIN.

Speccation of Letters Patent. Patented Apr. 26, 1921.

Application led August 25,1919. Serial No. 319,594.

To all whom it may conce/m:

` Be it known that I, NELSON M. L anGDoN, a citizen of the United States, residing at Mancelona, in the county of Antrim and State of Michigan, havey invented certain new and useful Improvements inStorage- Bins, of which the following is a specifica tion.

This invention relates tof storage bins and has for its object the provision of a str-ong, durable and inexpensive structure in which coal, grain or other. material may be stored and from which the materialmay be readily withdrawn. A particular object of the invention is to provide a structure whereby a i longitudinally traveling overhead bucket or carrier may be utilizedto deposit material in the bin or to withdraw the same material and all the material. may be withdrawn by the manipulation of Ythe bucket vwithout y moving the same transversely or requiring pose of which will presently appear.

an handling of the material to bring it into the path of the bucket.

The stated objects kof the invention and other incidental objects Awhich will appear in the course of the following`V description arel attained in such a mechanism ras is illustrated in theaccompanying drawings and the invention resides incertain novel features which will be particularly pointed out in the claims following the description.r y In the drawings:

Figure llisua side elevation of a storage bin embodying my improvements, showing the same located adjacent a railroad track whereby the material may be, transferred from the bin directlyto a car or ,vice versa.

Fig. 2 is avertical `transverse section.

In carrying out my invention, I. employ a` I binor receptacle which may be `constructed of any convenient or preferred material `and will generally be constructed of concrete or other plastic material which may be molded into the proper `formI at the location selected for the bin. `As shown most clearly in Fig. 2, the sides of the bin converge downwardly, as at 2, and the bottom 8 of thebin is rela-,l tively narrowso that only a small portion of the bin will have Va flat bottom, the

e downwardly converging sides 2 may have their upper terminals located at the ground surface 4; or they may be continued in vertically disposed .walls 5 to any desired height. The vertical,` walls will generally be employed inasmuch as the bin will vbe thereby l given greater capacity without occupying an excessive amount of ground space and a greater quantity of material may be stored `within a bin co-vering a given area. Upon the side walls 2, I provide abutments 6 in which the lower ends of posts 7 may be embedded or otherwise anchored.` These posts 7 converge slightly upwardly, as shown in Fig. 2, and are provided at intervals through the entire length of thebin. The posts are. disposed at corresponding points on the two sides of the bin and the upper ends of the corresponding posts support transverse beams or caps 8. Bracing plates 9 are secured to the opposite faces of the beam and the postsk at the meeting ends thereof, as clearly shown in Fig. 2, so that the `beams andr posts are rigidly connected and braced against lateral movement and` ample` space is provided for the scoop or bucket presently described. n ,V posts, I secure rails 10 lwhich extend the entire length of the bin and braces llare also secured tothe posts andthe said rails to lend rigidity to the structure andy brace the mem# bers against longitudinal movement. Ex-

tending longitudinally ofthe bin, preferably in the central vertical plane of the same,a track 12 isfsecured to land carried by vthe beams 8. A carrier including altrolley 13 e of any well-known or preferred form is Upon the` outer edges, of the .f

mounted to travel upon the saidtrack`12 and may be controlled. by a cable 14 extending from end to. end of the structure. f The isoperat'ed'in a wcll-knownmanner tojdump material Acontained therein into the bin and y also to take up or receivematerial stored in the bin and withdraw the same. ,f e In `r`Fig.` 2 I have indicated material stored in the bin and it will be noted ythat its n greatest height is in the central vertical longitudinal plane of the bin.. The bucketl lis directly over the apex of the material and will, of course, if lowered, enter the material at its highestpoint. As the quantity of material in the bin is reduced by `successive `withdrawals,a central depressiomas indicated by the dotted line 16 in Fig.` 2, will be ,formed in the stored material. Thisfdepression will continue to deepen" centrally as morematerial is withdrawn. When the base of the depression reaches or passes below the horizontal planevof the top .of thebin or of the upper extremities of the downwardly converging side walls 2, the side portions of the material will graviate toward the 'center thereof inasmuch as theV converging side walls do not furnish a stable support for the material. The bucket may thus be utilized to withdraw the entire quantity of materialVY from the bin without moving laterally and without requiring the material to be shoveled into the path of the bucket, and to facilitate the taking up of every particle of the .material bythe bucket or scoop the flat portion 3 ofthe bottom ofthebin will be justwide enough to accommodate the Width ofthe bucket so that the final operation of the bucketnwill act upon the entire surface of the extremebottom of the bin and none of the stored material will be left and lost.

` It will be readily noted that the same instrumentality which delivers material into the bin is utilized to withdraw the material therefrom and lIwthereby economize in the costofinstall'ationand also in the cost of n operation. The method of'operation is also simplified and material may be rapidly storedinthe bin'until the' same is filled to its Ycapacity andwhen it .isl desiredy to withdraw some or all ofthe material the desired result may be easily.l and rapidlylattained.

i) It will be noted thatl the supports forthe trackin tliepillustrated embodiment of the invention are anchored below the top of the bin andiwithin the same sothat the possibility ofthe. supports beinrdan'iaged `by chance; blows visl minimized. ,v2-Moreover, this arrangement `permits the use ofa comparatively large bin or storage receptacle without spreading the posts to suchl an extent that transverse trusses are needed to brace ya cable secured at its ends may be employed instead" of the track rails or beams shown.. The bucket'y may lbe of any well-known or preferred form operable to take up ory receive materialat one point and carry it to and deposit itat another point. 1

As previously noted, the drawings illustrate the bin located with one end adjacent a railroad track,vthereby expediting the transfer Vof material from a car tothe bin or from the 'bin to a car. Attheopposite'end of thebin,

a landing or platform be provided/so that material maybe transferredfrom supply trucks or wagons to the'bin or from the bin `to supply wagons or trucks. Y
